Embodiment

In order further to understand feature of the present utility model and technology contents, see also following about detailed description of the present utility model and accompanying drawing, yet the following drawings and embodiment only provide with reference to the usefulness of explanation, be not to be used to limit the utility model.

As Fig. 3, Fig. 4 and shown in Figure 7, the safety buckle of the utility model quick coupling, be used to be articulated in the safety buckle of a quick coupling 6 both sides, and can fasten be connected with quick coupling 6 connect mouth 7, its preferred embodiment comprises one and fastens handle 1, a clip pin 2, an elastic element 3, a draw ring 4 and a clamping sheet 5, wherein:

Fastening handle 1 is used to be hubbed at the body of rod of quick coupling 6, it comprises the inner face 13 of a buckling end 11, in contrast to operating end 12, the one adjacent quick couplings 6 of buckling end 11, one outside 14, and two sides 15 that connect inner face 13 and outside 14 in contrast to inner face 13; Wherein, buckling end 11 is provided with a pivot hole 111 that is used to be articulated in quick coupling 6, reach one and be used to fasten the gibbosity form buckling part 112 that connects mouth 7, inner face 13 is provided with the recess 131 of corresponding quick coupling 6 shapes, operating end 12 is provided with a pin-and-hole 16 that is communicated to recess 131, bi-side 15 are provided with a long strip clasp perforation 17 that communicates, and make clasp bore a hole 17 vertical connections in pin-and-hole 16, and bi-side 15 convex with a stop block 18 between clasp perforation 17 and outside 14 respectively, and stop block 18 is preferable is shaped as triangle.

2 activities of clip pin are arranged in the cylinder that fastens in handle 1 pin-and-hole 16, it has a front end 21 that protrudes in recess 131, and the rear end 22 of extend past clasp perforation 17, make front end 21 in order to directly being fastened on quick coupling 6, or fasten the clamping sheet 5 that is incorporated into quick coupling 6.

Elastic element 3 one ends are resisted against clip pin 2, the other end is resisted against in the pin-and-hole 16 that fastens handle 1, make elastic element 3 protrude in the recess 131 that fastens handle 1 with the front end 21 that its elastic force promotes clip pin 2, and then make front end 21 in order to directly being fastened on quick coupling 6, or fasten the clamping sheet 5 that is incorporated into quick coupling 6.

Draw ring 4 is an annular solid, and it passes clasp perforation 17 and the clip pin 2 that fastens handle 1, and can be stopped and can not overturn towards the outside that fastens handle 1 by the stop block 18 of fastening handle 1.

One upper end of clamping sheet 5 is provided with a support convex 51, one lower ends and is provided with a clip recess 52 that can supply clip pin 2 front ends to fasten, and the centre is provided with a corresponding pivot hole that fastens handle 1, and is articulated in the perforation 53 of quick coupling 6.

Structure characteristic and combination relation design, the i.e. safety buckle of the utility model quick coupling by above-mentioned fastening handle 1, clip pin 2, elastic element 3, draw ring 4 and clamping sheet 5.

Consult shown in Figure 4 again, the utility model preferred embodiment comprises the operating end 12 that fastens handle 1 and is provided with a groove 19 towards buckling end 11, pin-and-hole 16 is run through be communicated between recess 131 and the groove 19, and the rear end 22 that makes clip pin 2 is stretched on groove 19 places, make draw ring 4 pass clasp perforation 17 whereby and be stretched on the clip pin 2 of groove 19, just can make draw ring 4 spur 2 activities of clip pins.

Consult Fig. 3 and shown in Figure 6 again, the utility model preferred embodiment comprises in the pin-and-hole 16 that fastens handle 1 can make up a stop ring 161, structure by stop ring 161, make elastic element 3 one ends be resisted against clip pin 2, the other end is resisted against stop ring 161, make elastic element 3 have support, and prevent that it breaks away from pin-and-hole 16.And the shaft of clip pin 2 also can be provided with a portion of class 23, makes elastic element 3 one ends be resisted against the portion of class 23 of clip pin 2, and the other end is resisted against the stop ring 161 in the above-mentioned pin-and-hole 16.

Consult Fig. 5 and shown in Figure 6, be combined in the pivot 62 of known quick coupling 6 two side pin joint seats 61 during the utility model application implementation by the pivot hole 111 that fastens handle 1, buckling part 112 is stretched in the quick coupling 6 through fluting 63, can be used to fasten insert quick coupling 6 connect mouth 7 (consulting shown in Figure 7).And clamping sheet 5 53 is combined in pivot 62 by boring a hole, make clamping sheet 5 be positioned at a side that fastens handle 1, and the support convex 51 of its upper end is resisted against the upper limb of fluting 63, prevent that whole clamping sheet 5 from rotating, 52 of the clip recesses of lower end can be interlocked with the front end 21 of clip pin 2, preventing whereby that whole fastening handle 1 from overturning outward gets loose, and avoids quick coupling 6 and connects mouth 7 and separate, and reaches the effect that safety fastens.

Consult Fig. 8 and shown in Figure 9 again, when quick coupling 6 when connecing mouth 7 and need separate, as long as the user is towards the operating end 12 pulling draw rings 4 that fasten handle 1, and then the front end 21 that drives clip pin 2 shrinks, cause the clip recess 52 of the front end 21 disengaging clamping sheets 5 of clip pin 2, so remove its buckling state, just can fasten handle 1 switching outward, the buckling part 112 of one end gibbosity form is removed for the buckling state that connects mouth 7, so just can be made quick coupling 6 and connect mouth 7 and separate.

The effect that the utility model is reached is, fasten handle 1, and clamping sheet 5 can be used for being installed on known pipe joint 6 pivots 62 of knowing fast, therefore as long as not had the machine-processed fastening handle of safety fastening, do not take off known quick coupling 6, and change the outfit and go up the purpose that fastening handle 1 of the present utility model and clamping sheet 5 just can be reached the safety fastening, and because the utility model need not be changed whole quick coupling 6, can be more to save cost and to obtain safe effect.

It will be further appreciated that, the utility model fastens the clasp perforation 17 of

handle

1 and 15 places, bi-side between the outside 14 convex with a stop block 18 respectively, and the width that makes two stop blocks 18 is greater than draw ring 4, therefore when elastic element 3 promotion clip pins 2, when the front end 21 that causes clip pin 2 fastens with the clip recess 52 of clamping sheet 5, the stop block 18 that draw ring 4 will be fastened handle 1 stops and can not outwards overturn, have the user only and spur the outwards upset that stops that draw ring 4 breaks away from stop block 18, therefore the utility model can prevent that draw ring 4 from being touched upset accidentally and causing the phenomenon that clip pin 2 is drawn by mistake, can reach to prevent to fasten the effect that handle 1 unclamps accidentally.

The above; it only is preferred embodiment of the present utility model; be not in order to limiting protection domain of the present utility model, so use equivalent replacement that the utility model specification and accompanying drawing do or change etc. all should be contained within the protection domain of the utility model patent such as.
